jQuery mobile:动态更新可折叠标题会导致样式丢失

Question

动态更新现有可折叠元素的标题标签文本后，样式将消失，即使我在更新后调用.collapsible({refresh: true})

jsFiddle: http://jsfiddle.net/RAxn5/(点击'Break it'链接看看我的意思)

HTML:

<div id="set" data-role="collapsible-set">
    <div data-role="collapsible" id="set1" data-collapsed="false">
        <h2 class="section_title">Section 1</h2>
        <ul data-role="listview">
            <li><a href="#"><h3>item 1</h3></a></li>
            <li><a href="#"><h3>item 2</h3></a></li>
            <li><a href="#"><h3>item 3</h3></a></li>
        </ul>
    </div>
</div>
<a href="#" id="break">Break it</a>

JS:

$('#break').click(function() {
    $('#set1 h2.section_title').text('Now my style is gone!');
    $('#set1').collapsible({refresh: true});
});

Answer 1

添加到span.ui-btn-text，不添加到h2

$('#set1 span.ui-btn-text').text('Now my style is gone!');

Answer 2

一个简单的解决方案(虽然有点粗糙)是找到按钮设置的span并更改它，而不是更改父id。

$('#set1 h2.section_title').find('.ui-btn-text').text('Now my style is gone!');
